Using the E-Trunk is really easy. First, use the Top - Lock adapter to attach it to your e - bike. It doesn't take long to set up. When you're done with your ride, just give it a 'click' to remove it. For storage, you can put all your essentials like snacks, a small tool kit, or extra clothes inside. To use the bottle mount, simply place your water bottle in it. When it comes to safety, make sure to attach a rear light to the dedicated space and keep the 3M Scotchlite reflector clean for maximum visibility. As for maintenance, since it's waterproof, you can wipe it down with a damp cloth after a dirty ride. Avoid using harsh chemicals as they may damage the material. Store it in a dry place when not in use.
